The Sun Hydraulics RVCAKBV (Material Number: RVCAKBV) is a ventable, pilot-operated, balanced piston relief cartridge designed to regulate pressure effectively. This normally closed pressure-regulating valve opens to the tank port when the inlet port pressure reaches the set threshold, allowing it to throttle flow and maintain desired pressure levels. It features a vent port for remote control via other pilot or 2-way valves, offering precise and smooth operation with minimal noise and moderate speed. The valve is equipped with a 150-micron stainless steel screen to protect the main stage orifice, and it can handle maximum pressure at port 2, making it suitable for cross-port relief circuits\u2014though spool leakage should be considered in such applications. Notably, this valve is not recommended for load-holding scenarios due to potential leakage. The RVCAKBV model incorporates Sun's floating style construction, minimizing internal binding risks from excessive installation torque or machining variations. It supports systems using phosphate ester fluids when configured with EPDM seals but can be damaged by petroleum-based substances. With a capacity of 15 gpm (60 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve offers reliable performance across various settings. The response time is typically around 10 milliseconds, and the valve leakage at 110 SUS (24 cSt) measures approximately 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Installation requires specific torque settings: valve installation torque ranges from 30-35 lbf\u00b7ft (41-47 Nm), while locknut torque ranges from 80-90 lbf\u00b7in (9-10 Nm). The adjustment screw features an internal hex size of 5/32 in (4 mm), ensuring ease of customization for diverse applications.
